Receiver Drier
WARNING: This page is about a different car, the 2019 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
The receiver drier stores high-pressure liquid and the desiccant bag mounted inside the receiver-drier removes any retained moisture from the refrigerant.
The receiver drier is externally mounted to the LH side of the A/C condenser.
